Okay, I've been using AdSense for about two years now and I still don't understand the concept. I'm sure I could figure it out if I read and read, but I'm too impatient to do the proper research.

What is the method to earn more money? Do you want the most amount of clicks in the smallest amount of impressions? In other words, does 10 clicks out of 1000 impressions yield higher earnings than 10 clicks out of 5000 impressions?

If you have fewer advertisements per page, does that also increase your earning potential? For example, does one click on a page with one advertisement yield more than one click on a page with three advertisements?

Thanks in advance.
